F.ASTE1\`I'I1\TGr` THE HANDLES TO PICKS AND OTHER TOOLS.

Specification of Letters Patent No. 29,155, dated July 17, 1860.

To all whom it may concern:

Be it known that I, JOSEPH H. FISHER, of Placerville, in the county ofEldorado and State of California, have invented a new and ImprovedFastening for Connecting Picks and other Tools to Their Handles; and Ido hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, forming a part of this specification, in which- Figure l, is asectional view showing my invention. Fig. 2., is a rear end view. Fig.3, is a perspective view of the wedge, and Fig. 4c, a detached view ofthe gib and key.

Similar letters of reference in each of the several figures, indicatecorresponding parts.

My invention consists in the combination with a handle which extendspartly into the eye of the pick and has a socket in its rear end and twoshouldered spring straps at its sides, of a portable wedge constructedwith a tongue and a gib and a key seat or slot, in the manner and forthe purpose hereinafter set forth.

To enable others, skilled in the art, to make and use my invention, Iwill proceed to describe its construction and operation.

A, is the pick having a` Haring eye as usual.

B, is the handle constructed so as to extend into the eye a sufficientdistance to be firmly bound by the metal inclosing the same, and thus beprevented from splitting.

C, C, are spring metal straps attached respectively by bolts a, a, tothe upper and lower edges of the handle. These straps are tapering inform and extend a suflicient distance beyond the rear end of the handleso as to pass entirely through the eye when the pick and handle aresecured together.

A shoulder b, iS formed on each strap, So that the pick shall not slipup on the handle.

E, is a wedge to be inserted at the rear end of the eye. This wedge hasa tongue c, formed on it, and through this tongue, a slot c, is cut.lhen the wedge iS driven into the eye and between the spring metalstraps, from the rear of the pick, its tongue enters a socket f, cut inthe rear end of the handle, and its transverse slot e, comes in linewith similar slots cut through the handle. Thus driving in the wedge,forces the spring straps apart and causes them to bind as wedges againstthe eye in such manner as to lirmly retain the pick in the handle. Nowby inserting a gib f, and key g, through the transverse slot e, in thetongue of the wedge and in the handle, the wedge and handle will bedrawn firmly together and the union between the handle and pickperfectly accomplished.

My invention provides a good and substantial fastening for connectinghandles to picks and other tools, so that they can be easily takentherefrom to admit of sharpening and other necessary repairs withoutinjury to the handle; also that any number of picks or tools may beadjusted to one handle, thereby lessening the cost.

What I claim as my invention and desire to secure by Letters Patent, is-

The combination with a handle which extends partly into the eye of thepick and has a socket in its rear end and two shouldered spring strapsat its sides, of a portable wedge constructed with a tongue and a giband a key seat or Slot.
